Pneumatic casters support up to 8,400 lbs per caster and feature air-filled or foam-filled tires that provide superior shock absorption and traction on rough terrain. CasterHQ stocks pneumatic casters in 6" to 16" tire diameters with both traditional air-fill (for fields, outdoor terrain, unpaved surfaces) and foam-fill (maintenance-free, puncture-proof for industrial use) — available with heavy-duty swivel and lock options.

Pneumatic (air-filled) tires grip uneven surfaces like concrete with expansion joints, asphalt cracks, gravel, and dirt far better than solid wheels because the tire flexes and conforms to terrain. The cushioning effect reduces vibration and impact transmission to the equipment, protecting sensitive cargo and reducing operator fatigue during hand-pushing. Pneumatic casters are the standard for outdoor equipment, field service, construction sites, and agriculture where solid wheels would bounce and lose control.
Air-filled pneumatic casters provide the best cushioning and grip but require periodic pressure checks and tire maintenance; they can puncture on sharp objects. Foam-filled pneumatic casters deliver 85-90% of the cushioning of air-filled tires while being maintenance-free and puncture-proof; they're ideal for industrial environments where downtime for flat repairs is unacceptable. CasterHQ recommends foam-fill for manufacturing facilities and air-fill for occasional outdoor use.
